Technical Field
[0001] The utility model belongs to the technical field of jaw crusher discharge openings, and in particular relates to a jaw crusher discharge opening width adjustment device. Background Art
[0002] Jaw crusher is commonly known as jaw crusher. It consists of two jaw plates, a moving jaw and a static jaw, forming a crushing chamber. It simulates the movement of two jaws of animals to complete the material crushing operation. It is widely used in the medium-sized crushing of various ores and bulk materials in the mining, smelting, building materials, highways, railways, water conservancy and chemical industries.
[0003] Due to long-term severe impact during operation, the jaw plate is prone to wear, which changes the distance between the movable jaw and the static jaw, and changes the width of the discharge port, resulting in the discharge particle size not meeting the requirements. In order to ensure that the crushed discharge particle size is qualified, it is necessary to frequently adjust the width of the discharge port during the use of the jaw crusher.
[0004] At present, there are two methods for adjusting the width of the discharge port in jaw crusher systems at home and abroad. One method is to loosen the originally locked adjustment seat, and then use the manual adjustment push rod to drive the adjustment seat forward, and then change the total thickness of the pad behind the adjustment seat to change the width of the discharge port of the jaw crusher. This method requires at least two workers to operate each time the width of the discharge port is adjusted, and the equipment is shut down for half an hour. For large jaw crushers, it even takes 1-2 hours. Frequent long-term shutdowns to adjust the width of the discharge port will seriously affect the production efficiency of the entire production line, with high comprehensive costs and great losses. Another method is to set up double smooth wedges, and the wedges are in contact with each other through smooth inclined surfaces. The relative position of the double wedges is changed manually or hydraulically to change the width of the jaw crusher's discharge port. This method also has the problem of time-consuming and labor-intensive if it is adjusted manually. In addition, since the double wedges are subjected to lateral forces during equipment operation, it is necessary to add left and right push rods or use a hydraulic system to maintain pressure for a long time to prevent the wedges from shifting. However, long-term pressure maintenance using a hydraulic system is prone to hydraulic oil leakage, and mechanical tightening using left and right push rods has the problem of mechanical locking mechanism loosening and failure, and the reliability is not high. Based on this, the utility model provides a jaw crusher discharge port width adjustment device to facilitate adjustment. Utility Model Content

[0024] Preferably, the screw rod 402 is rotatably connected to the inside of the fixed block 401 through a bearing 403 , and the other end of the screw rod 402 is connected to the output shaft of the servo motor 407 .
[0025] When in use, the screw rod 402 can be stably rotated inside the fixed block 401 along the inner ring of the bearing 403 , thereby improving the rotation stability of the screw rod 402 .
[0026] Preferably, the mounting block 406 forms a threaded motion with the screw rod 402 through the thread sleeve 404 and the connecting block 405 .
[0027] During specific use, when the silk sleeve 404 moves, the installation block 406 moves along with the silk sleeve 404 through the connecting block 405, thereby conveniently driving the support mechanism to move.
[0028] Preferably, the supporting mechanism comprises a supporting rod 5, a movable rod 6, a limiting block 7 and a protrusion 8, the movable rod 6 is inserted and moved inside the supporting rod 5, the limiting block 7 is fixed to the right side wall of the movable jaw 2, and the protrusion 8 is fixed to the top of the mounting block 406.
[0029] During specific use, the support mechanism can push the position of the movable jaw 2 when the adjustment mechanism 4 is working, thereby adjusting the distance between the movable jaw 2 and the fixed jaw 1, so as to achieve the purpose of adjusting the width of the discharge port.
[0030] Preferably, two limit blocks 7 and two protrusions 8 are provided, and the limit block 7 is rotatably connected to one end of the support rod 5 , and the protrusion 8 is rotatably connected to one end of the movable rod 6 .
[0031] During specific use, the support rod 5 and the movable rod 6 are rotated between the limiting block 7 and the protrusion 8, so that the support rod 5 and the movable rod 6 will not be affected by the interference caused by the movement of the adjustment mechanism 4.
[0032] Preferably, a rubber air cushion 9 is connected to the side wall of the fixed block 401 close to the movable jaw 2 , and the rubber air cushion 9 is attached to the side wall of the movable jaw 2 .
[0033] During specific use, the rubber air cushion 9 reduces the influence of the movable jaw 2 on the adjusting device, so as to prevent the adjusting device from being squeezed and deformed, thereby affecting normal use.
[0034] Working principle: When the jaw crusher is working, if the distance between the fixed jaw 1 and the movable jaw 2 needs to be adjusted, the servo motor 407 is started, and then the output shaft of the servo motor 407 drives the screw rod 402 to rotate along the inner ring of the bearing 403 inside the fixed block 401. At the same time, the thread sleeve 404 moves along the thread on the surface of the screw rod 402, and the installation of the connecting block 405 and the mounting block 406 also moves. Then, the movement of the mounting block 406 drives the movable rod 6 to move forward, and the tilt between the movable rod 6 and the support rod 5 is adjusted. The inclination angle will become larger and larger, and then the support rod 5 pushes the movable jaw 2 close to the fixed jaw 1 to change the distance between the two, thereby completing the adjustment of the width of the discharge port of the jaw crusher, and achieving the purpose of adjusting the width of the discharge port, thereby realizing the automatic adjustment of the width of the discharge port. At the same time, the movable jaw 2 will swing during operation. In order to reduce the collision with the adjusting device, we install a rubber air cushion 9 on the side wall of the fixed block 401 close to the movable jaw 2, and then reduce the collision between the movable jaw 2 and the adjusting device through the rubber air cushion 9, so as to avoid the adjusting device from being squeezed and deformed, affecting normal use.
[0035] It should be noted that the jaw crusher is an existing mature technology. When working, the movable jaw 2 moves and cooperates with the fixed jaw 1 to complete the crushing of materials. The distance between the fixed jaw 1 and the movable jaw 2 is called the discharge port. At the same time, in the drawings of the specification, since the jaw crusher is an existing mature technology, only the fixed jaw 1 and the movable jaw 2 are drawn.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
